Ive seen some cute versions of overall's, but in general in my area where I live, overalls tend to be for old men who work outside, or pregnant woman or kids. Thye are ok I guess, but I dont own any. I dont thinkof them as hick so much as I do just not my style. If you like them, wear them...thats all I can tell you. IF you sport it and you like it, who cares anyways!
im not a big fan of them although i do wear them when doing shop work or stuff outside mostly because of the extra pockets and they keep me from getting crap on my shirts but i would never wear them except for when they serve a practical purpose
